Could you replace its value in 2 places to just eu-west-1? When the last character is there it’s actually signifies an availability zone in the region, not region itself. The corrected lines should look like below.

s3:
region: eu-west-1

and

emr:
ami_version: 4.5.0
region: eu-west-1

###in bucket

Your value is just snwlpk-logs. It should be properly referenced. I suspect this is the reason you are getting that error. If this is the actual bucket where your Clodfront distribution writes the logs to then it should look like

raw:
in:
- s3://snwlpk-logs

Note the protocol (s3) in font of the bucket name. You also could use s3n.

Could you privide the link to your updated configuration file, please? Alternatively, paste it in here (with credentials removed) in between a pair of triple ticks to retain the indentation as shown below:

Also where do you run your EmrEtlRunner? Is it in the same region? Any proxy engaged?
